1965 Chevy Longbed

I am trying to sell my dads 1965 Chevy Longbed Truck. Clear title. Everything is still original, 350, & 3 still on tree. It is in GREAT condition (no rust). Runs GREAT!! He was driving it until 3 weeks ago when he decided to sell it. We were trying to figure what it's worth. Can anyone help me out?

A lot will depend on dents dings, big window, custom cab, power steering brakes, what options are on it, and location, generally more in the east that the west, can you post pics, would be a big help. anywhere from 1,500 to 6,000
